"Is the group leader in a particularly good mood because of some happy event?"
After Luo Yanqing left the lab, a researcher surnamed Wang nudged He Wei with his shoulder and asked.
"I bet it's because Comrade Kang is visiting the institute."
He Wei said importantly, "Do you still remember that time before the New Year, when the group leader was in an especially good mood all afternoon and even let us off before 7:30?"
Researcher Wang thought about it and had a sudden realization, "Ah, that's why!"
"It's most likely that. Come on, let's go back to the dorm to get our lunch boxes. We might just see Comrade Kang in the canteen," He Wei said with a smile, signaling to Researcher Wang to leave with him and also calling out to Wen Siyuan, and the three of them left the lab.
The canteen.
Having got their meals, He Wei and his colleagues were about to head to the table they had their eye on when they saw Kang Li smiling and talking to Luo Yanqing, entering the canteen with ease.
